Matlab r2013a doesn't recognize any compiler in order to protect a model

Question

I have a problem with my r2013a Matlab.

I want to protect a model using Simulink.ModelReference.protect('test') command. For this I have to configure my compiler. I'm using the mex -setup command, and the xpcsetCC -setup command.

At first, Matlab says that is all ok with the compiler, but when i try to execute the Simulink.ModelReference.protect('model') command it shows an erro saying that there is no compiler avaiable. Here are the sequences of commands:

PART 1 - 'mex -setup'

INPUT

mex -setup

OUTPUT

Welcome to mex -setup.  This utility will help you set up  
a default compiler.  For a list of supported compilers, see  
http://www.mathworks.com/support/compilers/R2013a/win64.html 

Please choose your compiler for building MEX-files: 

Would you like mex to locate installed compilers [y]/n?

INPUT

   y

OUTPUT

 Select a compiler: 
 [1] Intel C++ 12.0 (with Microsoft Software Development Kit (SDK) linker) in C:\Program Files (x86)\Intel\ComposerXE-2011\ 
 [2] Intel C++ 12.0 (with Microsoft Visual C++ 2010 linker) in C:\Program Files (x86)\Intel\ComposerXE-2011 
 [3] Microsoft Software Development Kit (SDK) 7.1 in C:\Program Files (x86)\Microsoft Visual Studio 10.0 
 [4] Microsoft Visual C++ 2010 in C:\Program Files (x86)\Microsoft Visual Studio 10.0 

 [0] None 

 Compiler:

INPUT

 4

OUTPUT

 Please verify your choices: 

Compiler: Microsoft Visual C++ 2010  
Location: C:\Program Files (x86)\Microsoft Visual Studio 10.0 

Are these correct [y]/n?

INPUT

y

OUTPUT

PART 2 - 'xpcsetCC -setup'

INPUT

xpcsetCC -setup

OUTPUT

 Select your compiler for xPC Target.


  [1] Microsoft Visual C++ Compilers 2010 Professional in C:\Program Files (x86)\Microsoft Visual Studio 10.0

  [0] None


  Compiler:

INPUT

1

OUTPUT

Verify your selection:

  Compiler: Microsoft Visual C++ Compilers 2010 Professional
  Location: C:\Program Files (x86)\Microsoft Visual Studio 10.0

  Are these correct [y]/n?Y

  Done... 

Until now everthing is ok, but next there is an error:

Part 3 - Simulink.ModelReference.protect('test')

INPUT

 Simulink.ModelReference.protect('test')

OUTPUT

### Model reference SIM target (test_msp.mexw64) for model test is out of date because test_msp.mexw64 does not exist.
### Updating model reference SIM target for model: test
Warning: The model 'test' does not have continuous states, hence Simulink is using the solver 'VariableStepDiscrete' instead of solver 'ode45'.
You can disable this diagnostic by explicitly specifying a discrete solver in the solver tab of the Configuration Parameters dialog, or by
setting the 'Automatic solver parameter selection' diagnostic to 'none' in the Diagnostics tab of the Configuration Parameters dialog 
Warning: Using a default value of 0.2 for maximum step size.  The simulation step size will be equal to or less than this value.  You can disable
this diagnostic by setting 'Automatic solver parameter selection' diagnostic to 'none' in the Diagnostics page of the configuration parameters
  dialog 
  ### Build procedure for model: 'test' aborted due to an error.
  Error using Creator.protect (line 287)
  An installed compiler was not detected. Certain simulation modes, as well as host-based coder builds require that a compiler be installed. Please
  install one of the supported compilers for this release as listed at:

  http://www.mathworks.com/support/compilers/R2013a/win64.html

  MATLAB must be restarted after the compiler is installed.

I've already tried all different choices of available compilers. I also tried to choose no for the fist question of mex -setup ("Would you like mex to locate installed compilers [y]/n?") and choose the compiler manually. None of this worked.
